“I have used several of these adapters on different versions of the Raspberry Pi and had no problems, there is very little to set up and in the latest version of raspbian it is picked up and displayed on the GUI.
I have also used these on a HP Note book using Windows 7 to replace the poor in-built Wifi on the Note Book, Windows picked it up without problems.”
“Cannot get the adapter to connect up to my router which is a BT hub. Have tried several times, following the instrutions as per various Raspberry Pi handbooks but no luck. Will try again but running out of steam with it. Guess I'll have to link up to my hub with wire!”
